Abstract (en)
An optical analyzer system for identifying solid and liquid materials use near-infrared transmission spectroscopy combined with multivariate calibration methods for analysis of the spectral data. The device includes an optical concentrator (310) to increase efficiency of light transmission from the light source (305) through a sample aperture (320) to a sample holder (130). Near-infrared transmission spectroscopy is employed within either the 700 - 1100 nm or the 900 - 1700 nm wavelength range to identify solid or liquid materials and determine whether they match specific known materials. Uses include identifying solid (including powdered) and liquid materials with a fast measurement cycle time of about 2 to 15 seconds and with a method that requires no sample preparation, as well as quantitative analysis to determine the concentration of one or more chemical components in a solid or liquid sample that consists of a mixture of components. A primary application of such analysis includes detection of counterfeit drug tablets, capsules and liquid medications.
